DNA binding properties of 2ΚΉ-hydroxyflavanon and SCHIFF base derivative
Flavanoids a class of plant and fungus secondary metabolites. 2ΚΉ-Hydroxyflavanone was previously isolated from Mimosa pudica(L.) whole plant and was found to exhibit anti-inflammatory effects in vitro and binding with calf timus DNA. There are also reports on anti-inflammatory properties of compounds bearing flavanone/chromone nucleus. The aim of this work was to develop a synthesis of new azomethine compounds derived from flavanones, to examine their spectroscopic properties and interaction with DNA. 2ΚΉ-Hydroxyflavanone and thiocarbohydrazide were used as substrates in the synthesis. The obtained products were analyzed by 1H NMR spectroscopy, UVVis. Ultraviolet spectroscopy was used to analyze the chemical-physical properties. Mechanism of interaction of bioactive 2ΚΉ-hydroxyflavanone with calf thymus deoxyribonucleic acid (DNA) was studied employing UV absorption. 2ΚΉ-Hydroxyflavanon and 2ΚΉHFTCH are photostable in DMSO. The interaction of 2ΚΉ-hydroxyflavanone and its derivative occurs by the mechanism of intercalation. The change in the structure of the 2ΚΉ-hydroxyflavanone molecule by Schiff base modification leads to an increase in DNA-binding properties. High binding ability of 2ΚΉ-hydroxyflavanone with DNA may be useful for development of new anti-inflammatory and antimicrobial remedies.Π€Π»Π°Π²Π°Π½ΠΎΠΈΠ΄Ρ β ΠΊΡΡΠΏΠ½Π΅ΠΉΡΠΈΠΉ ΠΊΠ»Π°ΡΡ ΡΠ°ΡΡΠΈΡΠ΅Π»ΡΠ½ΡΡ

Influence of flavonone and hesperetin Schiff bases on the activity of ABC-transporters in Saccharomyces cerevisiae cells in the respiration process
A certain effect of flavonoids (hesperetin, flavonone, monohydroxy derivatives of flavonones and their Schiff bases of flavonoids ) on the ABC-transporters activity and the viability of the yeast cells Saccharomyces cerevisiae. Among of the studied compounds, derivatives of 6-hydroxyflavonone with thiocarbohydrazide and hesperetin with 2-aminobenzhydrazide at a concentration of 50 ΞΌmol stimulated the activity of ABC-transporters in the S. cerevisiae cells during the oxidation of glycerol during respiration. These compounds were not affect the viability of yeast cells and can be used in biotechnology as modulators of the ABC-transporters activity.ΠΠΏΡΠ΅Π΄Π΅Π»Π΅Π½ΠΎ Π²Π»ΠΈΡΠ½ΠΈΠ΅ ΡΠ»Π°Π²ΠΎΠ½ΠΎΠΈΠ΄ΠΎΠ² (Π³Π΅ΡΠΏΠ΅ΡΠ΅ΡΠΈΠ½Π°, ΡΠ»Π°Π²ΠΎΠ½ΠΎΠ½Π°, ΠΌΠΎΠ½ΠΎΠ³ΠΈΠ΄ΡΠΎΠΊΡΠΈΠΏΡΠΎΠΈΠ·Π²ΠΎΠ΄Π½ΡΡ
